BENJAMIN NORTHUP, OF ELMIRA, NEWV YORK, ASSIGNOR TO CONSTAN- I TINE 'BANTLEY, OF SAME PLACE.

POSITIVE SHUTTLE-MOTION FOR LODMS.

SPECIFICATION forming part of Letters Patent No. 367,838, dated August 9. 1887- Application filed September 23, 1884. Serial No. 143,773. (No model.)

To all whom it may concern:

Be it known that I, BENJAMIN NonTnUr, a citizen of the United States, residing at Elmira, in the county of Chemung and State of 1 New York, have invented a new and'useful Improvement in Positive ShuttleMotious for Looms, of which the following is a specifica tion.

My invention relates to the portions of a loom which have to do with the changing of the shuttle from'one carrier to the other in that class of looms wherein the fillingwire or weft-thread is wound on a bobbin and is carried, not thrown, through the warps from-one side to the other by sliding arms, which meet at a given point in thejouruey,when the bobbin is released automatically from one arm and taken by the other.

The object of the invention is to provide improved means for automatically releasing the hold of one arm of the shuttle at the in- I attain this object by the mechanism shown in the accompanying drawings, in which Figure 1 represents a front elevation of a portion of a loom, showing the application of my improvements thereto. Fig. 2 is a detail of the inner end of one of the traveling arms; and Fig. 3 is a side elevation of one of the spindles and its spring, showing also one of the hollow arms and its spring-latch and the end of the lever for actuating thespindle.

' Similar letters of reference refer to similar parts throughout the several views.

1 represents a portion of the main frame of a loom, and 2 are guides forthe shuttle-carrying arms L. To the outer ends of the shuttlecarrying arms pitmen 3 are connected, and these pitmcn are in turn pivoted to crankarms 4, secured to the shaft 5 of the oscillating wheel M. Motion is imparted to the said wheel by means of the shaft 6, cranks 7 thereon, rods 8, chains 18, passingover the pulleys 9, rods N, and chain or chains 20, attached to or passing round the wheel M.

10 is an upright secured to the lay-frame, and in this upright the shaft 5 is journaled.

'Below this shaft is pivoted the lever 0, its upper end extending in the path of the pin J on the wheel M. A B are angle-levers pivoted at d to said upright, and between the upper ends of said levers the lower end of the lever O swings.

11 are guides secured to the upright 10, and in these guides work the spindles H, around which are placed the springs E.

Onthe front of the oscillating wheel M, I project the pin J, which, when the wheel is moved to the right'point in either direction, strikes the rounded end K of the swinging lever O and moves it sidewise either to the right or left, as the case may be. This causes the lower end of the lever G to press against one or the other of the angle levers A and B. The angle lever, when thus moved, presses down on the corresponding spindle, H,which is wedgeshaped, just at the instant when the arm L,with its shuttle-holding springlatch l, is presented .to the opposite arm. The spindle strikes between the arm L and the spring latch I, and, being wedge-shaped, presses the springout, as shown by dotted lines in Fig. 2,

The two traveling arms are actuated by the same oscillating wheel which operates the lever O, andso all act in unison. \Vhen the wheel moves one way, one spindle is pressed down, and when it moves the otherway the other goes down, and the whole mechanism is so adjusted that the two arms approaching each other-one carrying the shuttle, the other one going to receive itmeet each other at just the right time and place to receive the downstroke of the spindle at the instant when the receiving-arm presses its spring-latch against the opposite end of the shuttle and clasps it.

Vhat I claim as my invention, and desire to secure by Letters Patent, is

The combination, with the frame, the shuttle-carrying arms having latches I, the wheel M, means for oscillating said wheel, and connections between said wheel and arms, of the angle-levers A B,pin J on saidwheel, lever O in the path of said pin, the spindles H H, operated by said levers A B, andthe springs E E on said spindles, substantially as and for the purpose specified.

BENJAMIN NORTHUP.
